Types of Rats & Mice in St. Louis
Norway Rat
The Norway rat, or brown rat, is a large, robust species with bodies up to 10 inches long, excluding the tail. Exceptional climbers and swimmers, they invade buildings from the ground or sewers, causing significant structural damage through gnawing. Their adaptability contributes to their reputation as formidable pests.
House Mouse
The house mouse, measuring 3-4 inches with a similar length tail, has smooth fur and large ears. Unlike the cautious rat, they're curious, quickly exploring new items, making them easier to catch but equally problematic in homes and businesses due to their exploratory nature.
Roof Rat
Roof rats, sleek and smaller than Norway rats, have tails longer than their bodies. Preferring high nests in attics or trees, they excel at climbing. Their diet of fruits, nuts, and seeds often leads them to raid kitchens and storage areas.
